My invention relates to improvements in or relating to photographic typesetting or composing machines.

Photographic type setting machines are known in which there is a groove,stop or other control element provided for each character contained onthe matrix table or the photographic support by means of which themovement of the film box feeding device is controlled. Furtherarrangements of this kind have been proposed in which on the use of aphotographic matrix and a control support an alteration of the opticalreproduction ratio is possible. In these arrangements the stroke of thecontrol lever determined by the control support is transmitted throughthe medium of a double-armed lever to the film slide, on the one handthe fulcrum of the double-armed lever rigidly connected with theobjective, and on the other hand the engaging point of the lever at thefilm box being, with the various optical adjustments, so displaced thatthe transmission ratio of the double-armed lever corresponds to theoptical transmission ratio at the time.

It is the object of this invention to provide for such a photographictype setting or composing machine a matrix plate of small dimensionswhich allows of a completely accurate and simple adjustment of theindividual characters into the optical axis and a suitable control ofthe film box.

To this end, according to the invention, the characters to beexposed arearranged adjacent and over one another in a chequered manner and arebrought into the optical axis by movement of the matrix plate such thatthe side edges of the table maintain their direction. For the purpose ofthe positioning, the matrix plate is securely connected to and movedtogether with a second plate in which are arranged fixing holes suchthat the position and distance of the individual fixing holes from oneanother correspond to the position and distance of the characters fromone another, a pin or the like which is inserted into the holeappertaining to the respective characters serving for retaining thevarious characters in the exposure position.

In order that the invention may be fully understood I will now describetwo embodiments thereof by way of example by reference to theaccompanying drawings, in. which:

Fig. 1 is a view of the whole machine partly in plan and partly insection through the optical axis.

Fig. 2 is a section on the line 1I-II of Fig. '1.

Fig. 3 is a. section on the line III-m of Fig. 1.

Fig. 4 is a front elevation taken in the direction of the arrow C ofFig. 1.

Fig. 5 is a perspective view of the matrix and perforated plate, and

Fig. 6 and '7 are views of a modified arrangeg, ment.

The characters are arranged above and adjacent one another in achequered manner on the transparent rectangular matrix plate I, which issecurely connected to and simultaneously 1o moved with the fixing plate2, which contains the perforations or holes 3. The matrix plate I slideswith the members 4 oh the machine plate 5 and. is controlled by aparallel motion linkage which is illustrated by the two pairs of levers6, I and 8, 9 in Fig.2. The two parallel levers 6 and 'l are pivoted atthe points In and I! to the machine plate 5 and are both pivotallyconnected to the movable plate l2. On thisplate I2 are pivoted twoparallel levers 8 and 9 which 29 are pivoted with their two other endsto the box l3, one side of which constitutes the fixing plate 2. Thematrix table I and the fixing plate 2 can, owing to this parallel motionlinkage, be moved in such a manner that their edges main- 25 tain theirdirection. The individual characters of the matrix plate can, in thisway, be brought to that position which they are to occupy relative tothe optical axis during the type setting. Each character is arranged onthe matrix plate with its line and one side at a constant distance withrespect to theaxis of the hole appertaining thereto, which is indicatedin the drawings, Fig. 5 by b and a respectively. The holes 3 in thefixing plate 2 are likewise arranged in a chequered manner and theyagree as regards their mutual posi-. tions wholly with the position ofthe characters on the matrix plate I, so that a hole 3 on the fixingplate appertains to each character on the 40 matrix plate I. The holes 3are so arranged that when a character on the plate I is brought into theposition for composing, the corresponding hole 3 on fixing plate 2 islikewise disposed entirely or at least approximately in the optical 45axis l4. This coincidence of the characters and the fixing holes 3 issuitably produced in that on preparing the matrix plate the individualcharacters thereon are positioned with the help of the alreadypreviously prepared perforated plate.

If, now, on using the photographic type setting machine a character isadjusted as is shown, for example, in Fig. 5 in respect to the characteror the letter u, then a pin l6 arranged on the machine frame is insertedinto the respective objective carrier i1 is displaced corresponding to Ithe desired projection ratio 2x11. In the same manner the film box isalso secured to the film box holder 25 which is displaceable inthe railguide 26 parallel to the objective axis, and with the roller 21 arrangedon the end thereof is pressed by the tension spring 28 on to a secondcam 29. Both cams 22 and 29 can either each be displaced by a hand leveralong a separate scale with corresponding divisions or graduations, orthey can be positively connected together as shown in Fig. 1, forexample by chain 30, so that on the adjustment of the lever arm 23 boththe objective l and also the film box 24 are brought to the settingsadjusted for the time being and are brought into the positioncorresponding to the focal length of the objective.

On the slide of the objective carrier ii is pivotally carried on a pin33, outside the principal plane of the objective IS, the two-armadjusting lever 3|, 32, the said pin 33 forming the fulcrum for themovement of the said lever. Arm 32 of the lever carries at its free enda sleeve 34, which is connected by a pin 35 to the adjusting slide 36,which slides in-the guide 3? which is secured also to the film boxholder 25 and can be displaced together with the latter by means of thecam 29. The film box 24 is arranged on the slide 38 and is displaceablein the rail guide 39 of the film box holder 25 at right angles to theaxis of the objective by means of the iron bar 40 connected thereto,which slides past the electromagnets 4|. The holding magnet 42 issecured to the film box holder 25 so that the iron bar 40 connected tothe film box slides freely in front of the two groups of magnets if noneof them is energized.

When, now, the-apparatus is to be adjusted to a. definite character orletter, the fixing pin 16 is first withdrawn from the hole 3 of thefixing plate 2' in which it happens to be inserted, and the plate 2 isthen moved in such a manner that the pin I6 can be inserted into thehole 3 appertaining to the character to be adjusted. In order that thefilm box 24 can be adjusted to the correct breadth of the character theplate 2 is provided with grooves or recesses 43 by. the length of whichthe width of the character is determined,which corresponds to theadjusting hole appertaining to the groove. If, then, the adjusting lever3|, 32 is swung in the direction of the arrow 44 (Fig. 1), the nose 45of the lever 46 pivoted to said adjusting lever slides behind the plate2; in this way a stop or shoulder, on lever 46 strikes against a pin 4!whereby the nose 45 is forced into the respective groove and strikes theend thereof so that in this way the movement of the adjusting lever hislimited. Since at the end of the movement of adjusting lever 39 thecarrier magnets 4i are energized, while at the same time thepositioningmagnet 42 is deenergized, the subsequent movement of lever3!, counter to the direction of arrow 44 is, transmitted in the ratioany to the adjusting slide 36 and by reason of the fact that theelectromagnets take with them the iron bar 4@ connected with thefilm-box 24 to the film=box itself. At the end of this movement, thecarrier magnets 4| again become deenergized, while at the same time thepositioning magnet 42 is energized with the result that by means of theiron bar 40 the filmbox 24 is held fast.

In the arrangement according to Figs. 1-5, the matrix plate'and the twoother adjustable parts of the machine, namely the objective and thelight sensitive film, lie in parallel planes. This is very inconvenientin practice as in this case the matrix plate must be displaced in thevertical direction. An arrangement in which the matrix plate liesperpendicularly with respect-to the two other moveable parts and isconsequently carried horizontally and can be displaced in a horizontalplane, is illustrated in Figs. 6. and 7. In this arrangement the axis ofthe character to be exposed does not coincide with the axis of theobjective l5 but the light ray coming from the matrix plate I is guidedat an angle through a light deflecting means, for example a prism 49, tothe objective l5 and from there straight out again to the lightsensitive film. In order that the projection ratio any 'may remain thesame as previously, the path of the light ray 48 through the prism 49 tothe matrix plate I (Fig. 6) must again be (:0-A) +A=a:. The projectionratio corresponds also in this case always to the ratio of the lever armmm of the adjusting lever 3|, 32,

so that in this case also the character breadths are transmitted in amagnification corresponding to the optical ratio to the movement of thefilm .roll.
